[0029] Combine the following Figure 1-Figure 3 The technical solution provided by the utility model is described in more detail.

[0030] like Figure 1-Figure 3As shown, the safety belt rigid cold impact test device provided by the utility model comprises a bracket 1, a driving device 4, a weight 2 and a clamping jaw assembly, wherein: the driving device 4 is fixed on the bracket 1, the clamping jaw assembly is used to clamp or release the weight 2, the driving device 4 is connected to the clamping jaw assembly for driving the clamping jaw assembly to rise and fall; a limiting track 11 is provided on the bracket 1, the side of the weight 2 extends into the limiting track 11, and the weight 2 is slidably connected to the limiting track 11 when it is freely falling or rising and falling driven by the driving device 4.

[0031] The weight block 2 is a standard weight block 2 for the seat belt rigidity cold impact test, and is a steel weight block 2 with a mass of 18 kg. Figure 2 As shown, the weight block 2 is a disc-shaped structure.

[0032] In the seat belt rigidity cold impact test device of the present embodiment, the driving device 4 can drive the clamping jaw assembly and the weight block 2 clamped in the clamping jaw assembly to rise and fall. When the weight block 2 rises to the target height, the clamping jaw assembly releases the weight block 2, and the weight block 2 falls along the limiting track 11 to impact the test specimen. There is no need to manually lift the weight block 2 to the target height, and there is no need to manually release the weight block 2. The operation is convenient and quick, and the labor intensity is reduced. The weight block 2 moves under the limit of the limiting track 11, which prevents the weight block 2 from causing safety accidents when falling, thereby improving the safety performance.

[0033] As an alternative embodiment, see Figure 2 and Figure 3 As shown, the limiting rails 11 of this embodiment are vertically arranged, and the limiting rails 11 are fixed to opposite sides of the bracket 1 .

[0034] The above-mentioned limiting track 11 is used to limit the movement of the weight block 2 along it, preventing the weight block 2 from deviating from the track when it falls freely or rises and falls under the drive of the driving device 4. In particular, it can prevent the weight block 2 from deviating from the track when it falls freely, affecting the personal safety of the operator.

[0035] See also Figure 2 and Figure 3 As shown, the driving device 4 includes a telescopic cylinder, which is vertically arranged to drive the weight block 2 to rise and fall vertically.

[0036] As an alternative embodiment, see Figure 2 and Figure 3 As shown, the safety belt rigid cold impact test device also includes a mounting groove 5, the mounting groove 5 is connected to the telescopic end of the driving device 4, the clamping jaw assembly is connected to the opposite sides of the mounting groove 5, the two sides of the weight block 2 are fixed with an axle rod 21, and the clamping jaw assembly can clamp the axle rod 21.

[0037] See also Figure 2 As shown, the mounting groove 5 is a U-shaped groove. When the clamping jaw assembly clamps the shaft 21 of the weight block 2, the upper part of the weight block 2 extends into the mounting groove 5. Figure 2and Figure 3 As shown, the telescopic end of the driving device 4 is connected to the mounting groove 5, thereby driving the mounting groove 5, the clamping jaw assembly and the weight 2 to rise and fall vertically.

[0038] As an alternative embodiment, see Figure 3 As shown, the clamping jaw assembly includes a cylinder 10 and a clamping jaw 3. The cylinder 10 is drivingly connected to the clamping jaw 3 to drive the clamping jaw 3 to close or open.

[0039] See also Figure 2 and Figure 3 As shown, when the driving device 4 drives the clamping jaw assembly and the weight 2 to rise to the target height, the cylinder 10 drives the clamping jaw 3 to open, the clamping jaw 3 no longer clamps the shaft 21, and the weight 2 descends along the limiting track 11 and hits the sample. Among them, the cylinder and the clamping jaw 3 can adopt the cylinder clamping jaw assembly in the prior art, and its structure is not described in detail here.

[0040] As an alternative embodiment, see Figure 1 As shown, the safety belt rigid cold impact test device also includes a protective plate 6, which is fixed on the bracket 1 and forms a dust cover with the bracket 1.

[0041] The driving device 4, the clamping jaw assembly, the weight 2 and the limiting track 11 are all located in the dust cover. The dust cover plays a role of dust and corrosion prevention while protecting the safety of the inspector and preventing the weight 2 from hitting the outside of the dust cover.

[0042] As an optional implementation, the protection plate 6 of this embodiment is a transparent organic glass plate.

[0043] The structure has certain structural strength and is convenient for operators to observe the situation inside the dust cover from the outside.

[0044] As an alternative embodiment, see Figure 1 As shown, an opening door 7 is provided on the dust cover.

[0045] When it is necessary to take out or place a sample, the sample can be taken out by opening the opening door 7, which is convenient to operate.

[0046] As an alternative embodiment, see Figure 2 As shown, a support platform 12 is provided on the bracket 1. The support platform 12 is located below the weight block 2 and is used to support the sample.

[0047] During the rigid cold impact test of the safety belt, the sample is placed on the support platform 12, and the weight 2 falls along the limit track 11 to hit the sample on the support platform 12, so as to check whether the sample is qualified.

[0048] As an alternative embodiment, see Figure 1 and Figure 2As shown, a support leg 8 is provided at the bottom of the bracket 1, and a buffer pad 9 is fixed to the bottom of the support leg 8 to play a buffering role and protect the ground.

[0049] See also Figure 2 and Figure 3 As shown, when the seat belt rigidity cold impact test is performed, the sample (seat belt component) is placed on the support platform 12, and the opening door 7 is closed. The driving device 4 drives the weight block 2 to rise to the target height, and the cylinder 10 drives the clamping jaws 3 to open. The clamping jaws 3 release the weight block 2, and the weight block 2 falls along the limit track 11 and hits the sample (seat belt component) on the support platform 12. If there are no obvious cracks on the seat belt component, the test requirements are met. After the test is completed, the weight block 2 is clamped on the clamping jaws 3 again and waits for the next test.
